Question

登录页面-https://b2b.chiemsee.com/customer/account/login/ 成功登录页面后-https://b2b.chiemsee.com/customer/account/loginPost/ 我要转到的页面-https://b2b.chiemsee.com/damen

我提出了3个单独的请求： 1）获取CSRF令牌。 2）进行登录。 3）导航到我要访问的网址。

在我添加第三个请求之前，登录正常，将我带到loginPost/页，但现在它带我回到login/页。它与第三个请求中的cookie有关吗？

PHP：-

// login request one to get form_key

include('simple_html_dom.php');

$ch2 = curl_init();
curl_setopt($ch2, CURLOPT_URL, "https://b2b.chiemsee.com/customer/account/login/");
curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
curl_setopt($ch2, CURLOPT_COOKIEJAR, 'cookie.txt'); // to save cookie data for login
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true); // to get the html
$response2 = curl_exec($ch2);
curl_close($ch2);

$html = new simple_html_dom();
$html->load($response2);

$val = $html->find('input[name=form_key]');
$form_key = $val[0]->value;


// login request two to send form_key, username and password

$data = array(
    'form_key' => $form_key,
    'login[username]' => 'user',
    'login[password]' => 'pass',
    'send' => 'Anmelden'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://b2b.chiemsee.com/customer/account/loginPost/");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
curl_setopt($ch, CURLOPT_POST, true); // to send info
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt'); // to read data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // to get the html
$response = curl_exec($ch);
if (curl_error($ch)) {
    $error_msg = curl_error($ch);
    var_dump($error_msg);
    exit;
}
curl_close($ch);


// request three to open first category

$ch3 = curl_init();
curl_setopt($ch3, CURLOPT_URL, "https://b2b.chiemsee.com/damen");
curl_setopt($ch3, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
curl_setopt($ch3, CURLOPT_COOKIEFILE, 'cookie.txt'); // to read data
curl_setopt($ch3, CURLOPT_RETURNTRANSFER, true); // to get the html
$response3 = curl_exec($ch3);
if (curl_error($ch3)) {
    $error_msg3 = curl_error($ch3);
    var_dump($error_msg3);
    exit;
}
curl_close($ch3);
echo $response3;

Answer 1

我发现了问题所在。我没有使用以下命令将第二个请求中发送的新数据（用户名和密码）保存在cookie文件中：

curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); // to save cookie data for login

更新的代码：

// login request one to get form_key

include('simple_html_dom.php');

$ch2 = curl_init();
curl_setopt($ch2, CURLOPT_URL, "https://b2b.chiemsee.com/customer/account/login/");
curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
curl_setopt($ch2, CURLOPT_COOKIEJAR, 'cookie.txt'); // to save cookie data for login
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true); // to get the html
$response2 = curl_exec($ch2);
curl_close($ch2);

$html = new simple_html_dom();
$html->load($response2);

$val = $html->find('input[name=form_key]');
$form_key = $val[0]->value;

// login request two to send form_key, username and password

$data = array(
    'form_key' => $form_key,
    'login[username]' => 'user',
    'login[password]' => 'pass',
    'send' => 'Anmelden'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://b2b.chiemsee.com/customer/account/loginPost/");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // to avoid error
curl_setopt($ch, CURLOPT_POST, true); // to send info
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt'); // to read data
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); // to save cookie data for login
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // to get the html
$response = curl_exec($ch);
if (curl_error($ch)) {
    $error_msg = curl_error($ch);
    var_dump($error_msg);
    exit;
}
curl_close($ch);
//echo $response;

// request three to open first category

$ch3 = curl_init();
curl_setopt($ch3, CURLOPT_URL, "https://b2b.chiemsee.com/damen");
curl_setopt($ch3, CURLOPT_FOLLOWLOCATION, true); // to allow redirections
curl_setopt($ch3, CURLOPT_COOKIEFILE, 'cookie.txt'); // to read data
curl_setopt($ch3, CURLOPT_RETURNTRANSFER, true); // to get the html
$response3 = curl_exec($ch3);
if (curl_error($ch3)) {
    $error_msg3 = curl_error($ch3);
    var_dump($error_msg3);
    exit;
}
curl_close($ch3);
echo $response3;

2）进行登录。

该代码从来没有起作用，您只是没有足够的登录错误检查代码来实现它。

替换

$response = curl_exec($ch);
if (curl_error($ch)) {
    $error_msg = curl_error($ch);
    var_dump($error_msg);
    exit;
}
curl_close($ch);

使用

$response = curl_exec($ch);
if (curl_error($ch)) {
    $error_msg = curl_error($ch);
    var_dump($error_msg);
    exit;
}
$domd=@DOMDocument::loadHTML($response);
$xp=new DOMXPath($domd);
$login_errors=array();
foreach($xp->query("//*[contains(@class,'error-msg')]") as $login_error){
    $login_error=trim($login_error->textContent);
    if(!empty($login_error)){
        $login_errors[]=$login_error;
    }
}
if(!empty($login_errors)){
    throw new \RuntimeException("login errors: ".print_r($login_errors,true));
}
curl_close($ch);

，您会看到登录时出错。

通过cURL登录后如何导航到其他页面？
